CORVALLIS, Ore. (AP) - The Corvallis public school system says a high school student has been diagnosed as having meningococcal disease

The bacterial disease inflames the brain lining, can cause complications once it infects the bloodstream, and can be deadly. Transmission requires close and persistent contact, so it does not spread readily.

Symptoms are high fever, headache and stiff neck, and they usually appear in three to four days.

The school system said in a statement Wednesday the Corvallis High School student showed symptoms on May 31.

The Benton County Health Department is coordinating an investigation to see whether anybody needs preventive treatment, but few people are expected to.
